Subject: [PATCH 4/4] Fix deprecation warning on Rails 6.0

In Rails 6.0 the API for template handlers is changing, a template
handler must now take two arguments [1], the template and the source,
otherwise you will see the following deprecation warning:

```
DEPRECATION WARNING: Single arity template handlers are deprecated. Template handlers must
now accept two parameters, the view object and the source for the view object.
Change:
  >> #<Faml::RailsHandler:0x0000561d54608868>.call(template)
To:
  >> #<Faml::RailsHandler:0x0000561d54608868>.call(template, source)
```
